1. A magnetometer for sensing a magnetic field, comprising:

  • a solid state electronic spin system containing one or more electronic spins that are disposed within a solid state lattice, and that are substantially free of interaction with the solid state lattice;

    wherein the electronic spins are configured to align with the magnetic field in response to optical excitation radiation applied thereto; and

    wherein the electronic spins can be further manipulated by an external control so as to induce a precession of the electronic spins about the magnetic field to be sensed, the frequency of the precession being linearly related to the magnetic field by the Zeeman shift of the electronic spin energy levels; and

    a detector configured to detect output optical radiation correlated with the electronic spins, after the electronic spins have been subject to the optical excitation radiation and the external control, so as to determine the Zeeman shift and thus the magnetic field.
